Data transfer
8-96
Block FC 100 transfers the PLC data for tool management to DB4.
The PLC data is set up for 2 loading stations (DB71), one tool holder (DB72),
and the turret magazine (DB73).
The signals for DB71, DB72, and DB73 are described in section 8.4.2 "Signal
description".
The "Real MagLoc" parameter of FC 100 (number of locations on the turret
magazine) must be assigned values when FC 100 is called.
Block FB 110 controls the data transfer for tool management.
The block includes the following functions:
S
Acknowledge load/unload/relocate for 1st loading point
S
Acknowledge change for tool holder
S
Abort, i.e. negative acknowledgment for the above–mentioned functions
The acknowledgment for these functions can be enabled by the PLC via the
input parameter of FB 110, e.g. confirm load/unload via user key.
The default settings for the input parameters are for automatic acknowledge-
ment, so that block FB 110 can be used on test stations involving no further link
to the machine; (see Table 8-1). Automatic acknowledgment is performed by
means of interface signals from the tool management data blocks; each of
these can be skipped.
For data transfer with the turret FB 110 from STL source file TM_REV.AWL can
be used.

Note
MD 9673 CMM_TOOL_LOAD_STATION defines the interface via which the
magazine will be loaded or unloaded.
